UNIVERSAL JOINT.

dated January 10, 1882.

Application filed December 8, 1881. (No model.)

To all whom it may concern Be it known that I, EDMUND GARRIGUES, ofMassillon, in the county of Stark and State of Ohio, have invented auseful Improvement in Universal Joints, of which the following is afull, clear, and exact description.

My invention consists principally of a universal-shaft connection,joint, or coupling, the ball of which is formed with an oil-chamber, ofcasting the yokes upon the ball, of the method of casting the ball andyokeswhereby the journals and bearings of the coupling will be chilled,and of a chilled ball, in combination with the yokes having chilledgudgeons or bearings. Reference is to be had to the accompanyingdrawings, forming part of this specification, in which similar lettersof reference indicate corresponding parts in all the figures.

Figure 1 is a plan view ofmy improved joint or coupling. Fig. 2 is asectional elevation taken on the line x m of Fig. l, and Fig. 3 is asectional elevation taken through the center of the ball.

In making my improved joint or shaft coupling, the ball Ais first cast,using chills in the molds for forming the four journals a and asand-core for forming the central oil-chamber B. A mold is then formedup around the ball for casting the yokes D and E, and this is done insuch manner that when the metal is poured the journals a. serve aschills for casting the bearings d and eof the okes. In this manner thecouplingis made complete by two castings, and the journals and bearingsare of chilled metal. The natural shrinkage of the metal will reduce thediameter-of the bearings d and c sufficiently to make sufiicient playfor the easy and proper working of the coupling.

The oil-chamber B communicates with the journals a through the openings0, and is formed with the inlet-opening .g, as clearly shown in Figs. 2and 3.

The openings 0 are preferably formed by means of small projectionstormedon the ends of the chills used in casting the ball, whichprojections reach into the sand-core of the oilchamber.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent-- 1. In auniversal joint or coupling, the ballA, formed with the oil-chamber B, communicating with the bearings of thejoint, substantially as shown and described.

2. The unit'ersal joint or coupling, formed by casting the yokes D and Eupon the ball A, substantially as described.

3. The method herein described, of forming the universal coupling,consisting in first casting the ball, using chills for thejournals, and

then casting the yokes upon the ball in such manner that the journalsact as chills for forming the bearings of the )OkGS, substantially asset forth.

l; 4. The chilled ball A, in combination with tlie yokes D and E, havingthe chilled bean ings (l and e, substantially as described. EDMUNDGARRIGUES. Vi tnesses:
